The model OP3524 is a combined narrowcast demultiplexer and broadcast/narrowcast combiner with integrated power level monitoring and management capabilities. The OP3524 features four optical input ports (one carrying the DWDM narrowcast services and the other three for either a single four-way split or dual two-way splits of broadcast services) and five output ports (one narrowcast services pass-through port and four combined broadcast/narrowcast ports). Each OP3524 demultiplexes up to four DWDM wavelengths and is available in various wavelength combinations.

One broadcast optical signal can be equally split four ways or each of two independent broadcast signals can be split two ways, while the narrowcast carriers are separated by a four-channel ITU-grid demultiplexer (with models available for both 100 GHz and 200 GHz spaced ITU-grid channels). Each narrowcast optical carrier is then multiplexed with one of the common broadcast optical signals and passed to one of the four output ports. DWDM optical carriers whose wavelengths are not dropped by the demux are passed through to the DWDM output port.

As new video and/or data carriers are added to the system, or as the configuration of the network is changed, the power levels of the optical carriers can change. To ensure optimal network performance, the optical power level management feature of the OP3524 allows power levels to be realigned remotely via SNMP interface to an element management system or locally via the chassis power supply display or local craft port interface. With the OP3524, broadband networks can be easily expanded by adding optical wavelengths without needing to break physical connections or install optical attenuators to realign the optical carrier power levels. By adding optical narrowcast carriers, the OP3524 allows MSOs to offer new, revenue-generating services, such as digital video, video-on-demand, high-speed data and telephony, more easily and cost-effectively than ever before.

OP3334 Light-Plex^® Module

The Model OP3334 provides a single 1550 nm broadcast input port and four 1310 nm narrowcast input ports. The 1550 nm broadcast signal is split four ways for multiplexing with each of the four independent 1310 nm narrowcast signals through a minimum loss combiner, with the resulting signals passed to four broadcast/narrowcast output ports.

The OP3334 is a completely passive combiner and is housed in Aurora's standard single-width, half-depth passive products module.

The integration of splitting and combining functions into one half-depth module simplifies narrowcasting installations, improves efficiencies by reducing optical losses, and requires less rack space than alternative equipment.

The OP3334 is also used to combine signals in 1530–1570 nm band of four inputs with 1264.5–1357.5 nm passbands.
